VALVE MECHANISM.

Application iiled November 15, 1924, Serial No. 750,119, andr in Mexico.uly 7,1924.

My invention relates to valves, and it has for one object to provide avalve of com pact'` and rugged design which shall operate periodicallyto cause the discharge of a predetermined quantity of water from areceptacle.

Another object of my invention is to provide a valve of the classdescribed, wherein the rate of periodic operation may be easily and`eliiciently controlled.

A further object of my invention is to provide an automatic valve, whichshall be adaptable to existing sanitary installations, wherein aypredetermined charge of water is .to be periodically discharged from areceptacle.

`A still further object of my invention is to-provide an automaticvalve, which shall be adapted for quantity production methods ofmanufacture, the several parts of which may be readily made on existingmachinery and assembled with a minimum expenditure of time and of money.

' Vtith these and other objects and applications in mind, my inventionfurther consists in the details of construct-ion vand operation andarrangement, hereinafter set forth injthe accompanying description,claims and drawing, wherein f n Fig. 1 is a vertical sectional view ofone form of embodiment of my invention, with the valve in the openposition;

Fig.2 is a view, partially in section and partially in elevation, of oneapplication of my invention;

Fig. 3 is a view similar to Fig. l, ybut showing certain parts of myvalve rearranged so as to permit of another application; and

Fig. 4f is a view similar to Fig. 2, but further illustratingA thealternate application of the valve of Fig. 3.

In the illustrated form of embodiment of my invention shown in Figs. 1and 2, a valve 1 lcomprises a vertically extending tubular element 2having internally threaded lower and upper end portions 3 and 4respectively associated with a supply pipe 5 and a plug element 6. Thesupply pipe 5 communicates with a source of fluid (not shown). The plugelement 6 yhas a recess or groove 7 formed in the threaded surfacethereof so as to provide an outlet passage from the tubular element 2.`The dimensions of theV outlet passage 7, and, hence7 the rate offiow oft-hefluid therethrough, may be adjusted by moving the threaded plugelement 6 into or out of the threaded end t of the element 2. Theimportance of the variable outlet passage 7 thus formed will appear morefully hereinafter.

The lower end of the tubular element 2 isV provided with an enlargedconical portion 8 forming a` `valve seat 9 4and an annular shoulder 11.The portion of the element 2 intermediate the valve seat 9 and theadjustable plug 6 is provided with a plurality of radially extendingperforations 12 communicating with the supply pipe 5, and theseperforations 12 constitute the main outlet openings of the valve 1.

The outlet passages l2 may be closed means of-a vertically movablesleeve 13, a lower end portion of which is provided with a conicalsurface 14 constituting a valve disk for the valve seat 9. An upper endof the sleeve 13 is provided with a conical surface 15 adapted to engagea complementary surface 16 on the adjacent end of the element 2 when thevalve is closed, that is, when the conical surfaces 9 and 14.- are inengagement.

The sleeve 13 may be actuated to open and to close the valve 1 by meansof a float 17 of any well known design. The particular form of floatshown in the drawing comprises a circular base member 18 which is inthreaded engagement with a portion 19 of the vertically movable sleeve13. The base member 1 8 may be provided with perforations 21, wherebythey fluid passing through the passage 7 of the plug 6 may escape fromthe float `17. A casing 22 has a lower open end secured in threadedengagement to the base member 18 so that air may be trapped in theclosed end thereof, Vall as will appear more fully hereinafter. f

The extent of vertical movement of the sleeve 13 may be adjustablycontrolled by means of a tubular cap 23, which has an upper portionthereof in threaded engagement with the sleeve 13 and a lower angedportion 24 positioned to engage the annular shoulder 11. The flangedportion 24, as well as an adjacent side portion 25 of the cap 23, isprovided with perforations 26, permitting the passage of fluid from thevalve l when the sleeve l13 has been moved't-o disengage the lowercon-ical surfaces 9 and 14.

In order to illustrate the operation ofmyV invention, I have shown inFig. 2 the valve 1 associated with a receptacle27 containing a fluid28', the level of which is such as to cause the valve 1 to assume theopen position shown in Fig. 1. In this position, the fluid in the supplypipe 5 is permitted to discharge through the valve passages 12, and 26into the receptacle 27. The fluid thus supplied to the receptacle 27 maybe discharged therefrom through a siphon 29 which is effective only whenthe valve 1 is in said open posiof the fluid 28 inthe receptacle`27 mayfall rapidly while the valve lvremains open.

In operation, assuming the valve 1 open f andthe siphon 29 effective todischarge fluid from the receptacle 27, as shown in Fig. 1, the level ofthe fluid falls rapidly. As the Vlevel of the fluid falls, the valvedisk la moves into engagement with the valve seat 9, closing the outletpassages 12 and thereby preventing a further discharge of fluidtherefrom into the receptacle 27. llhe fluid, however, continues todischarge from the receptacle 27 until they siphon 29 becomes ineflee`tive. Y

The valve 1 nowremains closed until sufficient fluid hasv leal'redthrough the groove 7 of the adjustable plug 6 to raise the level of thefluid in the receptacle 27 to the point where the valve opens and theSiphon '29 again becomes effective,I whereupon a: second 'discharge offluid from the receptacle 27 occurs. Hence, it is apparent that thevalve 1 causes a vperiodic discharge ofv fluid from the receptacle 27'through the siplion 29 and that the period between successive dischargesmay be controlled by means of the plug 6.

A further` application of my invention is shown in Figs. 3 and if,wherein the valve parts of Fig. lare so rearranged as to permit theiruse in a receptacle 35 containing a fluid 3,6 whichis to be'inai'ntainedat a predetermined level. Fig. 3, it is apparent that the structuretherein disclosed differentiates over thatr of Fig. 1`

in the fact that the valve parts 2, 13 and 23 are inverted with respectto the float hase 1S and also in fact that the plug G and the supplypipe 5 are oppositely disposed with respect to ends of the tubularelement s. In'

the present instance, the plug G is screwer tightly in position so toprevent the passage ofI fluid through the passage 7 thereof.

Inoperation, assuming the level of the fluid 36 sufficiently low so thatthe valve disk lt is disengagedv from the. valve seat 9, the outletpassages 12 are opened, permitting fluid to pass from the supply pipe'though the passages 12 land 26 into the receptacle 35. The fluid 36continues to rise Vuntil it has reached the .desired level atwhiclr'time the Referring more especially to' Leanne@ float 17 causesthe closing of the passages 12. W hen fluid is removed from thereceptacle 35 through a discharge pipe 38, the valve 1 is again actuatedintothe open position shown in Fig. 3 and the foregoing cycle repeated.`

lWhile l have shown only two forms of embodiment of my invention, forthe purpose of describing the same and illustrating its principles ofconstruction and of operation, it is apparent that various changes andmodifications may be made therein wit-hout` departing fromk the spiritof my invention,-

and, l desire, therefore,that only lsuch limi.

tations shall be imposed thereon, as are indicated in the appendedclaims or as are de'- inanded by the prior art. l l l; claim: l f `1.
